Christopher Nolan gives the gift of another brainy blockbuster

'Inception' finds writer/director Christopher Nolan in familiar territory as his previous reality-bending works ('Memento,' 'The Prestige,' 'The Dark Knight'), and the result is something almost as thrilling to contemplate as it is to watch. Even if you now know a little about what 'Inception' is about, you don’t even know the half of it. Grade: A.
